Problems solved by technology
[0005] The prior art solutions mentioned above have the following defects: at present, the iron core is heated by placing the iron core on the furnace platform, and then heating the heating mantle on the furnace platform and the iron core. In the presence of oxygen, the oxygen will cause the iron core to oxidize during the heating process, thereby reducing the quality of the finished iron core

Embodiment
[0045] Example: refer to figure 1 , is the manufacturing process of a kind of transformer iron core disclosed by the present invention, and concrete steps are as follows:
[0046] S1: Remove the package of the coiled steel belt, put the unwinding rack into the reeled steel belt, adjust the center distance of the main shaft at the same time, tighten it, and hoist it into the unloading rack seat with a chain hoist. Match the blanking width according to the production materials, and at the same time adjust the depth of the upper and lower knives and the gap between the blades to specify the depth of the steel strip knife. After the blade is completely fixed, use cable paper or wrapping paper for trial cutting. If each piece can be cut completely without serious burrs, it can be unloaded.
[0047] The total width of the under wool shall not exceed 350mm, and the weight shall be below 75kg. Remove the burrs on the deburring machine on the two ends of the finished specification ma...

The invention discloses a manufacturing process of a transformer iron core, which belongs to the technical field of transformer manufacturing, and aims to provide a manufacturing process of a transformer iron core that improves the quality of the finished iron core. The main points of the technical scheme are as follows: S2: Wind the steel strip into an iron core; S3: Place the iron core on the hearth, cover it with a heating mantle, and then heat the iron core through the hearth; S4: Dip the iron core in paint, place it on the hearth in S3 Protective cover, the gas in the protective cover is extracted first, and the protective gas used to prevent the oxidation of the iron core is passed into the protective cover. The state of the protective gas is stable when the furnace is heated, and the heating cover will protect the cover, Both the hearth and the iron core are covered in it. The protective gas is passed into the protective cover, so as to prevent the oxidation of the iron core caused by oxygen mixing in the iron core, and improve the quality of the finished product of the iron core.
Description
technical field [0001] The invention relates to the technical field of transformer manufacturing, in particular to a manufacturing process of a transformer core. Background technique [0002] The voltage transformer is an indispensable instrument for measuring the voltage in the high-voltage circuit to ensure the normal operation of the high-voltage circuit and the normal operation of other instruments in the high-voltage circuit. Through the principle of mutual inductance, a working voltage U1 is introduced into the primary winding, and this voltage generates a magnetic flux φ in the iron core. According to the law of electromagnetic induction, a secondary voltage U2 is generated in the secondary winding. The voltage transformer thus converts the high voltage proportionally into a low voltage. The different voltages on the line are unified into the same voltage according to different ratios, so that an electrical instrument with one voltage specification can measure voltag...
